Operating Instructions

Also read the operating instructions of the equipment this

engine powers.

Pre-Start Checklist

• Check oil level. Add oil if low. Do not overfill.

• Check coolant level. Add coolant if low.

• Check fuel level. Add fuel if low.

• Check radiator, cooling air intake areas and

external surfaces of engine. Make sure they are

clean and unobstructed.

• Check that the air cleaner components and all

shrouds, equipment covers, and guards are in

place and securely fastened.

• Check that any clutches or transmissions are

disengaged or placed in neutral. This is especially

important on equipment with hydrostatic drive.

The shift lever must be exactly in neutral to

prevent resistance which could keep the engine

from starting.

WARNING: Lethal Exhaust Gases!

Engine exhaust gases contain poisonous carbon monoxide.

Carbon monoxide is odorless, colorless, and can cause death if

inhaled. Avoid inhaling exhaust fumes, and never run the

engine in a closed building or confined area.

Cold Weather Starting Hints

1. The cooling system must be filled with coolant

capable of providing proper protection against

freezing at the lowest temperature expected (see

Coolant Recommendations on page 5).

2. Be sure to use the proper oil for the temperature

expected. See Figure 3 on page 4.

3. Declutch all possible external loads.
